[PATCH v3 0/3] VFIO migration related refactor and bug fix

[Zhenzhong Duan <zhenzhong.duan@intel.com>]

PATCH3 refactors the VFIO migration blocker related code based on
suggestions from Joao and Cedric, so that code is simpler and
"Migration disabled" printed in right case.

But before that works, also found some hotplug bugs when testing
blocker adding failed case. PATCH1 and PATCH2 fix them.

See patch description for details.

Thanks

v3: Add PATCH1,2 to fix hotplug bug
    Fix bugs in PATCH3 Avihai and Joao pointed out

Tested vfio hotplug/unplug with vfio migration supported and unsupported cases,
including blocker adding failed case.
